To-aZZ whom t may concern: 4

'Be it knownV that I, JAMES G. BARBOUR, aI citizen of the United States, residing at' Canton, in the county of Stark and State; oi' Ohio, have invented certain new and use-g ful Improvements in Brick-Cut-Ol' Tables,1 of which the following is a specification. .l

My invention relates to brickcut-oi ta-; bles such as are used for dividing'the clayf column into bricks after said column has@ passed from the ordinary brick machine.; In the ordinary brick-cut-O tables suchas'- are in use at the present time rit is impossible. to cut a brick having an irregular face ori one provided with lugs or ribs withoutthe use of specially shaped platens to lguide the; lwires through the clay column during the' cutting opera-tion. Y

It is the object ot my invention to pro--f vide a brick-cut-oii table by means of which a brick having irregular face or 'one pro-1 vided with lugs or ribs may be cut without the use of any specially formed platen. v

A further object is to provide a device ot this character 'wherein 'no platen is used above the clay column. n g

A still further object is to'provide a de vice of this character in which it is not; necessaryto use a transversely slotted plate`n vbeneath the clay column for guiding thei wires, a still further object is to provide a 2 and S upon shafts 1,6,V and 17 respectively device ot this character which will produce a brick having a similar :tace upon each sidef TheseV objects ltogether with other objectsr readily apparent to those skilled inthe art may be attained by the construction andv mechanism illustrated in thev accompanying: drawings, although my construction may be embodied in a variety of other mechanical forms, the construction` illustrated being chosen by way of example.

'In the drawings Figure 1 is a side ele`l vation of the brick-cut-oli' table constructed in accordance with my invention, also show-l,

ing a portion of the end of the brick ma-A chine. Fig. 2 is a top plan view ofthe saine. F is a section taken on the line 3 3 of. Fig. 2. Fig. l is an enlarged side elevation of a portion of my brick-cut-oiitable. Fig. 5 is a detailed perspective view'showing one form of an upper track. Fig. G is a similar' view of a lower track. Fig.,7 is a perspective view showing one end of the. upper bar with the wire tension head and wire bracing bar secured thereto, showing a different form tot' track. Fig. 8 is a plan view of 'another form `rof upper track.` Fig. 9 -is a' similar view ofthe lower trackto be used therewith. A

n 1 represents the die of a brick machine 2,

such as is ordinarily used in thefstiiiinud process o'fbrick manufacture. As the clay column /3 issues from the niouthof the brick machine itis cut across at intervals by wires t y refer to corresponding vparts"1throughout theA several iiguresof the 4c, for rthe purposefof forming brick.` The wires are carried by a! cut-olil frame 5 byl means of the'bar 6. and tension heads 7 securedto `a bar 8.kk As' theywires pass through the clay column-they` pass through slots the vwhole devicetravels with the clay column. 'The rollers 14 kand tracks 15 are provided ifor said travelingv movement, suitable means being employed tovcarry said device stationary but during the cutting Operation with "the clay'coluinn and return it to its normal position. This much of the device is the ordinary construction in brick-cut-oif tables.-

In my devicel slidably mountvthe bars' carried by44 the cut-od frame 5. To any suitable part of the' device preferably to the ribs 12 otthe thrust plates 10 I attach tracks. ,such `as at 18. Numerous forms of tracks may be used for producing brick of different design, but fory the purpose of illustration I have shown throughout several views of the Vdrawings the specific'form of asy the one shown in my application, Serial No. 68415041 tiled March 15, 1912; Fins r19 or their equivalents areprovided uponthe bar 8 and ,engage the tracks 18. A lowerv The wires 4. are attached at their upper track which is used in cutting a brick such llO extremities to the hooks 24 upon the tension heads 7, said wires passing through the slots 11 in the ribs 12 of the thrust plates and between the platens 22 and 23, the lower extremities of said wires being attached to thehooks 25 upon thebar 6. .Said wires are' always held taut by means of the tension springs 26 upon the tension heads 7, it Y being possible to change the tension as del@ sired upon said wires by means of the wing nuts 27. The upper and lower wire bracing bars 28 and 29 respectively are secured to the upper and lower bars 8 and Y6 respectively, said wire bracing bars being provided with slots 30, which are adapted to accommodate the wires 4 ata point as near as possible to the clay column.

In the form of track shown in Figs. 1 to 6 inclusive I have shown a track provided with a curved groove 31, said groove adapted to be engaged by the pins 19 and 20 or their equivalents. In the form of track shown in Fig. 7 I prefer to use merely a bar having a face provided with alternate lugs land depressions 32 and33 respectively, said'l face formingv a cam track. For this formV of track I prefer to use a roller 34 instead of a pin. By the use of this form of track a brick is produced having alternate ribs and grooves `upon both faces. In the form of track shown in Figs. 8 and 9 I prefer to use a flat bar having'a lug and depression 35 and 36 respectively near each extremity, the lugs and depressions being reversed in the upper and lower tracks. By this form of track I produce a brick having four lugs and four depressions upon ,each face thereof, each lug tapering from the edges of the brick toward the center thereof and vanishing into 40 kthe opposite groove. Numerous other forms of track may be used for forming different designs of' brick, the present forms being shown merely for illustration. By using a v'straight track it is also possible to cut a brick with a straight wire cut face with this device.

The opera-tion of the device is as follows:

The clay column 3 as it issues from the mouth of the brick machine 2 is continuously moving across the platens 22 and 23, and between the thrust plates 10. At predetermined intervals the whole device is caused to move forward with the clay column upon the rollers 14 and tracks 15. At the same time the cut-off frame is caused to reciprocate upon the base 13 of the device thereby drawing the wires 4 through the clay column and throughl the `grooves 9 in the opposite side plate 1() and into the grooves 11 in the rib 12,

thus dividing the clay column into bricks. At this point the reciprocatory motion ceases and the whole device is returned on the rollers 14 to the normal position which is shown in Figs. 1 and 2 of the drawings. The meansr for causing these operations of the machine are of ordinary construction and are used upon devices of this character at present in use and as they form no specic part of the present invention it is not thought necessary to show them. As the cut-oi-frame reciprocates transversely of the device the sliding bars 6 and 8 are caused to reciprocate longitudinally upon the shafts 16 and 17 by means of the pins 19 traveling upon the tracks 18. This longitudinally reciprocating of the bars 6 and 8 causes the wires 4 to be reciprocated in the same manner, the cut at the upper face of each brick thus formed conforming with the upper trackv and the cut at the lower face of each brick being of the same shape as the lower track. As the wires 4 are held in a straight line between the wire bracing bars 28 and 29 the face of the brick thus cut will form a straight line between the upper and lower edges at any point between the ends of said brick, but this line need not necessarily be vertical as the upper and lower ends of the wires may be oscillated in opposite directions as by means of the form track shown in Figs. 1 to 6 inclusive of the drawings. As shown in these figures the upper and lower extremities of each wire travel in reverse arcs thus forming a brick having a concave- .conveX face upon either side.4 In the form of track shown in Fig. 7 the lower track may be a duplicate of the upper track shown or it may be just the reverse, that is it may be provided with'a depression directly beneath each lug upon the upper track and with a lug directly beneath each depression upon the upper track. By means of the former construction, a brick is produced having alternate ribs and grooves upon each side while with the latter construction a brick is produced having a series of alternate lugs and depressions along the upper edge of each side, said lugs vanishing into depressions at the lower edges and the depressions terminating in lugs at the lower edges. By means of the track shown in Figs. 8 and 9 a brick is formed having two straight sides with four lugs and four depressions upon either side. Numerous other forms of brick may be produced by slight changes in the form of track, but it is not thought necessary to illustrate any further constructions of tracks.
